Application October 4,

1 Claim.

The invention relates to a portable base and more particularly to a portable base for electric motors.

The primary object of the invention is the pro- 5 vision of a base of this character, wherein an electric motor can be conveniently fastened in place for proper association with machinery to be driven thereby, the-base being of novel construction and is portable.

Another object of the invention is the provision of a base of this character, wherein the same is made of two sections, the upper section being latched to the lower section and said upper section is adapted to have fastened thereto an electric motor for driving machinery while in-association with these sections is a plug switch which is susceptible of automatic operation in the connection of the motor with the source of current supply and disconnection of the same.

A further object of the invention is the provision of a base of this character, which is simple in construction, thoroughly reliable and effective in operation, light in weight yet strong, durable, and inexpensive to manufacture and install.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses an the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure l is a fragmentary perspective view of a work bench showing the base constructed in accordance with the invention applied and having an electric motor mounted thereon for driving a jig sawing machine.

Figure 2 is a fragmentary vertical longitudinal sectional view through upper section of the base and motor.

Figure 3 is a top plan view of the bottom section of the base.

Figure 4 is a sectional view on the line 4-4 of Figure 2 looking in the direction of the arrows.

imilar reference characters indicate corresponding parts throughout the several views in the drawing. Referring to the drawing in detail, A designates a portion of a work bench or other like support while bolted or otherwise secured thereon is a machine B, in this instance a jig sawing machine of a standard construction. This support A is adapted to carry the portable base constituting the present invention and hereinafter fully described.

1937, Serial No. 167,319

The portable base comprises a lower foundation section III and an upper interfitted separable section II, these sections in this instance are preferably made from aluminum although the same may be made from any other suitable material. The lower section IE! is formed with a fiat body portion having preferably an open center I2 while upstanding from opposite longersides are the vertical side walls I3, one end of the said section being open while the opposite end is closed by an upstanding vertical end wall M.

The upper section II is preferably provided with an open center l5 and at three edges thereof are downturned flanges I6, these being at one end and at the opposite longer sides thereof. This upper section I I at the remaining open end thereof is formed with lugs I! to be accommodated in slots I8 provided in the closed end or the end wall It of the lower section Ill. The upper section I I is telescopically insertable in the lower section II] and the closed end of this upper section has engageable therewith a double-pronged latch I ll vertically swingable upon a pivot journaled in the sides I3 of the lower section ID, the latch I9 being provided with pintle eyes 2| receiving the pivot 26 while centrally of this latch is a depressible ear 22 engageable by a spring 23 urging said latch I9 to latching position with the upper section I I when fitted within the lower section Ill. In this manner the upper section II is separable from the lower section II]. The upper section, has bolted or otherwise made secure thereto an electric motor 24 while the lower section I I! is bolted or otherwise made fast at 24' to the support A. The motor 24 through the connections 25 and 26 operates or drives the machine B.

The lower section has fitted therein an electric plug socket fitting 21 while the upper sectioncarries an electric plug fitting 28 and in this manner separable electrical connection between the motor 24 and a feed current wire cable 29 is had. When the upper section II is separated from the lower section ID, the connection is automatically disengaged, that is, the plug 28 from the socket 21. Thus on separating the section II from the section I I! the motor 24 with the section I I attached thereto is readily portable.

The lugs l1 cooperate with the latch I9 in separably fastening the upper section I I in the lower section It], these constituting the base for the motor.

What is claimed is:

A base of the kind described comprising a lower foundation section provided with a bottom,

supporting section at two points thereof for the retention of the lugs in the clearances and hold ing the said sections'separably interfitted with each other, the end walls of the said sections being in closing relation to the opposite open ends thereof when the sections are interfitted with each other.
